Ancient magma plumbing found buried below moon"slargest dark spot
By Eric HandOct. 1, 2014 ,1:00 PM
Scientists have found a nearly squarepeg underneath a round hole—on the moon. Several kilometers below OceanusProcellarum, the largest dark spot on the moon’s near side, scientists havediscovered a giant rectangle thought to be the remnants of a geologicalplumbing system that spilled lava across the moon about 3.5 billion years ago.The features are similar to rift valleys on Earth—regions where the crust iscooling, contracting, and ripping apart. Their existence shows that the moon,early in its history, experienced tectonic and volcanic activity normallyassociated with much bigger planets.
